Residual stress Stress corrosion cracking Ultrasonic shot peening Water jet peening
In order to verify stability of residual stress improvement effect of peeing for mitigation of stress corrosion cracking in components of PWR plant, relaxation behavior of residual stress induced by w ater jet peening(WJP) and ultrasonic shot peening(USP) on surface of alloy 600 and its weld metal was investigated under various thermal aging and stress condition considered for actual plant operatio n. In the case of thermal aging at 320-380°C, surface residual stress relaxation was observed at the early st...
